Using a model system of glass particles, researchers from Penn found "solid bridges" formed by smaller-size particles between larger ones. The same bridges were present in suspensions of clay, a common component of natural soils. These structures provided stability, the team found, even when a moving channel of water threatened to wash the particle clumps away. Image credit: Jerolmack laboratory
